[0023] The present utility model will be further described below with reference to the drawings.

[0024] As Figure 1 and Figure 2As shown in the figure, the shaft slag discharging device of an embodiment of the present utility model includes a derrick 1, a chute 2, a spray pipe 3, a nozzle 4 and a water pipe 5. The chute 2, the spray pipe 3 and the water pipe 5 are all arranged on the derrick 1. The spray pipe 3 is located above the chute 2 and is horizontally arranged. The chute 2 is inclined. The length direction of the spray pipe 3 is perpendicular to the length direction of the chute 2. The length of the spray pipe 3 is greater than the width of the chute 2. The nozzle 4 is arranged on the spray pipe 3 and faces the chute 2. The water pipe 5 is connected to one end of the spray pipe 3.

[0025] In this embodiment, the spray pipe 3 is made of stainless steel pipe, which has the advantages of corrosion resistance and not being easily deformed.

[0026] The derrick 1 is provided with a water pipe 5 and a spray pipe 3. When the skip 6 dumps the muck into the chute 2, the water injected into the spray pipe 3 through the water pipe 5 can be sprayed onto the chute 2 through the nozzle 4. The length of the spray pipe 3 is greater than the width of the chute 2, and the spraying range can better cover the dumping area, so that the sprayed water can inhibit the generation of dust above the chute 2, reduce the environmental pollution during operation, and play a protective role for the operators.

[0027] As Figure 3 shown, in this embodiment, a plurality of nozzles 4 are arranged at intervals on the spray pipe 3, and the plurality of nozzles 4 are arranged on the spray pipe 3 at equal intervals. By arranging a plurality of nozzles 4 and making them arranged on the spray pipe 3 at equal intervals, the water in the spraying area can be distributed more evenly, and a better dust suppression effect can be achieved even at the edge part of the chute 2.

[0028] A plurality of water spraying holes 41 are formed on the surface of the nozzle 4, so that the water sprayed by a single nozzle 4 can cover a larger range and achieve a better spraying effect.

[0029] Specifically, the distance between two adjacent nozzles 4 is less than 0.5 meters. Controlling the distance between two adjacent nozzles 4 within a reasonable range can achieve a better spraying effect with as few nozzles 4 as possible. Specifically, the edges of the spraying areas generated by two adjacent nozzles 4 need to overlap each other to generate a continuous water curtain, eliminate the spraying dead corners and achieve a better dust suppression effect.

[0030] As Figure 1 and Figure 4 shown, fixing members 7 are arranged on both the upper and lower sides of the spray pipe 3. One side of the fixing member 7 is welded to the derrick 1, and the other side of the fixing member 7 is welded to the spray pipe 3. The spray pipe 3 is tubular and is not easy to be directly fixed on the derrick 1. By arranging the fixing members 7 to fix both the upper and lower sides of the spray pipe 3, the stability of the spray pipe 3 can be effectively improved, the loosening phenomenon of the spray pipe 3 after long-term use can be avoided, and the reliability of the device can be improved.

[0031] Due to the long length of the spray pipe 3, fixing members 7 are arranged at both ends of the spray pipe 3.

[0032] As Figure 1 and Figure 2 shown, a support member 8 is further provided below the chute 2, and one end of the support member 8 away from the chute 2 is arranged on the ground. Since only the top of the chute 2 is connected to the derrick 1, in order to ensure the stability of the chute 2, the support member 8 needs to be provided below the chute 2. Multiple support members 8 can be provided so that the chute 2 has a strong load-bearing capacity, can withstand the impact force when the muck is dumped, and prevent the chute 2 from deforming.

[0033] Furthermore, one end of the support member 8 away from the ground is welded to the derrick 1. To achieve a better support effect, a reinforcing plate (not shown in the figure) is provided at the bottom of the chute 2, and the support member 8 is welded and fixed to the reinforcing plate, thereby reducing the pressure received at the bottom of the chute 2 and preventing the support member 8 from causing protrusions on the surface of the chute 2.

[0034] As Figure 4 shown, a connecting pipe 9 is further provided between the spray head 4 and the spray pipe 3. The connecting pipe 9 is a stainless steel bellows pipe, and the connecting pipe 9 is detachably connected to the spray pipe 3. The connecting pipe 9 can be bent by a certain degree, thereby adjusting the spraying angle of the spray head 4. By setting the connecting pipe 9 to be shorter, the connecting pipe 9 can be fixed at a certain angle after adjustment and will not change its spraying angle automatically during the spraying process. Thus, the specific spraying position can be flexibly adjusted according to the actual operation conditions to meet the requirements of various operation conditions.

[0035] In this embodiment, the connecting pipe 9 is threadedly connected to the spray pipe 3, enabling the connecting pipe 9 and the spray pipe 3 to be quickly disassembled and assembled. When blockage or other situations occur and it is necessary to clean the connecting pipe 9 and the spray head 4, only the connecting pipe 9 needs to be removed, without having to remove the entire spray pipe 3, which is convenient for maintenance.

[0036] As Figure 3 shown, one end of the spray pipe 3 is provided with an end cap 31. The end cap 31 is threadedly connected to the spray pipe 3, and a water inlet joint 32 for connecting the water supply pipe 5 is provided on the end cap 31. After opening the end cap 31, the inside of the spray pipe 3 can be cleaned, thereby reducing the probability of blockage of the spray head 4. After cleaning, the end cap 31 can be directly screwed on to achieve sealing, without causing the spray pipe 3 to leak water.

[0037] To improve the reliability of the connection, at least one annular groove (not shown in the figure) can be provided on the surface of the water inlet joint 32, and one end of the water inlet joint 32 away from the end cap 31 is made smaller to facilitate the water pipe 5 to be sleeved on the water inlet joint 32.

[0038] In another embodiment, end caps 31 are provided at both ends of the spray pipe 3, enabling the spray pipe 3 to be opened from both ends, which is more convenient for maintenance. In addition, water can be supplied to the spray pipe 3 from both ends, which is beneficial to increasing the spray water volume and achieving a better spray dust suppression effect.

[0039] The water inlet joint 32 provided on the end cap 31 facilitates the connection of the water pipe 5. To prevent the water pipe 5 from becoming loose, the water pipe 5 is a flexible pipe that can be bent conveniently, so that it can be laid along the derrick 1 and fixed on the derrick 1. The weight of the water pipe 5 is borne by the derrick 1. In this embodiment, cable ties are used to fix the water pipe 5 on the derrick 1. Laying the water pipe 5 along the derrick 1 can also prevent the water pipe 5 from being overly bent, resulting in poor water flow, and can also prevent interference with the operation due to the water pipe 5 being suspended.

[0040] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components thereof can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
